I take pictures of insects (and arachnids). Jumping spiders are my favorite type of spider to take pictures of because they’ll sit there and pose for the camera while doing tiny war dances. They’re also really low risk for spiders. Typically they won’t even try to bite you - they’re having too much fun making themselves “look big”. So the picture represents something that makes me - “Cat” - happy - “grin”. BTW: the nickname isn’t from the animal cat - it’s from Red Dwarf.
